31 pairs of spinal nerves |
Ganglion | knot-like mass of nerve tissue outside of CNS |
Afferent nerves | sensory - carries impulses from body to CNS |
Efferent nerves | motor - carries impulses from CNS to muscles and glands |
Dendrites | brand out of cell body like trees. Sends impulses toward cell body. Where stimulus begins. |
Synapse | space between axon of neurons and dendrites of the next. Tells you to move. |
aphasia | inability to communicate |
dysphasia | difficult speech |
gyrus | one of the folds on the brain. plural - gyri |
hypothalmus | controls temperature, sleep and appetite. |

epilepsy | Seizure |
Multiple sclerosis (MS) | degenerative inflammatory disease of the CNS. Attacks myelin sheath in the spinal cord and brain leaving it sclerosed or scarred. Interrupts the flow of nerve impulses |
Nerves | bundles of dendrites and axons that travel together. |
ganglioneuroma | tumor of nerve tissue outside the brain. |
Parkinson's disease | Degenerative. Deterioration of nerves in the brain stem's motor system. Gradual onset of symptoms. |

meningomyelocele | hernia of spinal cord and meninges. |
ALS | amyotrophic lateral sclerosis |
MS | multiple sclerosis |
